Eponym Oswald Lohse, German astronomer (1845–1915)

Lohse is a crater in the Argyre quadrangle of Mars, located at 43.7° South and 16.8° West. It is 155.5 km in diameter and was named after Oswald Lohse, a German astronomer (1845-1915).[1]

Nearby prominent craters include Hartwig over a crater diameter north, the huge Greeley to the northeast, Green and Roddenberry to the southeast, Helmholtz under a crater diameter southwest and Arkhangelsky about two crater diameters nearly west-northwest.

The crater is very eroded. The uplifted area in the center contains gullies.[2] Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak.[3] The peak is caused by a rebound of the crater floor following the impact.[4]
